IMPROVEMENT IN LIQUID-METERS.

Specification formingpart of Letters Patent No. 108,804, dated November1, 1870.

'Toall whom it may concern .eflicient means for measuring water, so thatthe quantity discharged from a service or other pipe may be accuratelyascertained and registered; and it consists in operating, in acylindrical chamber,-by the pressure of the water,

a radial arm or wing, and in openingand closiug induction and dischargevalve ports by means of a falling weight, which is raised by the arm orwing, and in the mode of actuating the register, as will be hereinaftermore fully described.

In the accompanying drawing, Figure 1, Plate 1, represents a front viewwith the valveport cover off. Fig. 2, Plate 1, is a vertical section ofFig. l on the line am. Fig. 3, Plate 2, is a view of the meter from theback side with the side plate ofi', showing the movable weight and themanner in which it operates upon the valves. Fig. 4, Plate 2, is a Viewof the front with the front plate off, showing the radial wing, thevertical fixed radial plate, and the front valve-port.

Similar letters of reference indicate correspondin g part-s.

A is the casin g, which is a longitudinal section of a hollow cylinder,with a coveringplate at each end. B is the front plate, and G is theback plate. The case A rests in a horizontal position on the bed-pieceI). E is a vertical fixed partition, which fills the interior of thecylinder. F is the arbor of the radial and oscillating wing. One end ofthis arbor is supported by the partition E, the other end by the frontcovering-plate, B. G is the radial and oscillating wing attached to thearbor F.

By the partition E the casing A is divided into two compartments orchambers, O and H.

The principal compartment 0 is the waterchamber, in which the wing G ismade to 0perate. The other compartment, H, is the wateniuductionchamber, where the weight I op crates. h

J is a vertical fixed partition-plate, which extends from the centralarbor, F, to the casing, and forms an abutment, which, with theoscillating arm G, divides the water-chamber into two compartments,which are filled and discharged alternately as the valves are opened andclosed. K and L represent the valves. A front view of K is seen in Fig.4. Both are attached to a spindle, which passes through or is supportedby the vertical plate J Onehalf of the port-openings of each valve is oneach side of the plate J, and each valve is so arranged that these portsare opened and closed-alternately. K is the valve in theinduction-chamber H, and L is the valve over the eductionports in thecovering-plate B. M is the eductiou-chamber, and to N the discharge-pipeis attached.

The water enters the chamber H through the pipe M underpressure, andpasses through the valve K and the ports in the partition E, on one sideof the partition-plate J, and forces the wing G upward and around thecenter of the casing, carrying with it a crank, P, which is fast to thearbor F, which, in its rotating motion, comes in contact with and liftsthe weight I and carries it up past the center, where the weight, whichturns loosely on the arbor F, isthus carried past the center of itsgravity, it drops, and its descending force changes the position of thevalves, opening a porton one side of the plate J and. closing a port onthe other side for each valve every time the weight thus falls.

B and S are bars, attached by pivots to the valve in the chamber H.These bars are supported and guided in recesses in the stationary bar T,which is fast to the partition E. U is a curved plate attached to thecasing A, which acts as. a stop to limit the descent of the weight, asseen in Fig. 3. As the weight drops it strikes the ends of one or theother of the bars E S, and forces it down suificiently to change thevalve before it strikes the stop U.

By thus opening and closing avalve-port in each compartment of thewater-chamber every time the weight is caused to fall, the water isreceived and discharged into and from those compartments alternately,and the operation is continued as long as the pressure and flow of theWater is suflicient to operate the win g G. V represents spring-packingon the outer end of the wing G.

It will be seen that by the action of the weight the valves are changedsimultaneously. At the front or e'duction side the port of the i'ullchamber is opened and the other ort is closed, and at the otherorinduction s de the operation is reversed.

Each discharge is registered bymeans of the ordinary multiplyingmechanism usually employed for the purpose, which is actuated by theratchet and pawl seen in Fig. 1.

WV is the ratchet-wheel, and X is a springpawl, confined by clips on thefront of the meter. Y is a cam on the projecting end of the centralarbor, F. At every discharge of water or strike of the wing G the camraises the pawl, which moves the ratchet. one tooth. The pawl is hvld upto its work by the spring Z, and its back movement is produced by therecoil of the spring Z.

The discharge-pipe is attached at N, pro- 'vided with a stop-cock, sothat the water acts stantially as and for the purposes described.

2. The water-chamber 0, divided into two compartments by means of afixed partitionplate, J, and an oscillating wing, G, by which the wateris received and discharged alternately therefrom, substantially asdescribed.

3. The cam Y, pawl X, and ratchet U, by means of which-motion isimparted to the registering mechanism, all arranged substantially asdescribed.
